Abstract

The wireless communication device enables access to the Internet from the wireless LAN terminal, notifies the wireless LAN terminal of the situation of the wireless connection with the public wireless communication network, and thereby causes anxiety of the user at the time of connection to the network. This is alleviated.

The radio communication device detects the external NW usage information and notifies the radio LAN terminal, thereby improving the processing capability of the radio communication device and reducing the anxiety of the user when connecting to the public radio communication network.

When the radio communication terminal uses a mobile radio communication device that accesses the Internet using a public radio communication network, the communication load using the public radio communication network is reduced, and the Internet access environment is improved.

When the terminal device makes a connection request, the authentication unit authenticates the terminal device based on the authentication information previously stored in the storage unit. The encryption unit executes encryption processing based on the password previously stored in the storage unit. This prevents leakage of authentication information.

The wireless LAN terminal registers in advance by getting off reservation information and a self-identification identifier. When the vehicle is near the stop, the identifier is checked and the getting off reservation information is notified to the wireless LAN terminal. Thereby, the passenger who carries a wireless LAN terminal can get off at desired stop.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless communication system, and more particularly to a wireless communication system in which a wireless communication device uses a public wireless communication network when a wireless communication terminal used by a user connected to the wireless communication device accesses the Internet. A wireless communication device and a wireless communication terminal.

The present invention also relates to an authentication method for specifying a device to be communicated with, and a wireless communication device and a wireless terminal device using the same.

In addition, the present invention relates to a driving management system that executes vehicle management by providing information on getting off guidance (hereinafter referred to as getting off information) to a passenger using a wireless communication function built in a public transport vehicle such as a bus or a train. .

In recent years, various wireless communication systems, such as a mobile telephone and a wireless LAN (Local Area Network), have become widespread and are widely used because of their good accessibility. For example, a home LAN is easily established as a wireless LAN, a mobile phone is used to send and receive e-mails, or a home page on the Internet is routinely performed at the place of going out.

In addition, wireless LAN services in vehicles in which a relatively long time of boarding, such as a bus or a train, are performed have been considered. In a wireless communication system for realizing this wireless LAN service, a wireless LAN is constructed by installing a wireless communication device for a wireless LAN as a wireless base station in a moving vehicle. In addition, the radio communication apparatus has a function for connecting to a cellular phone network which is a public radio communication network as an access method to the outside such as the Internet. Thereby, it is possible to connect to the Internet via a wireless communication device and a public wireless communication network from a terminal such as a wireless LAN used by a user, such as a notebook personal computer in a mobile vehicle.

Examples of the public wireless communication network include a cellular system and a PHS system. Especially, a system using the cdma2000 1xEV-D0 system is known as a high-speed wireless communication system. See, for example, Japanese Patent Laid-Open No. 2002-300644.

However, in the above-described conventional wireless communication system, for example, wireless LAN, there are problems shown below.

The connection between the wireless communication device and the public wireless communication network is performed as necessary when there is access from the wireless LAN terminal to the outside such as a WEB server on the Internet. For this reason, when the wireless LAN terminal requests access to a predetermined home page, for example, the wireless communication device first starts a connection with a public wireless communication network, and after the connection is completed, the wireless communication device starts to the desired home page. Initiate access. However, when connecting to a public wireless communication network from a mobile vehicle, the connection may require a long time due to a change in the radio wave environment. In particular, a public wireless communication network in which PPP (Point to Point Protocol) is used, for example, a Personal Handyphone System (PHS) or a Code Division Multiple Access (CDMA) scheme called "cdma2000 1xEV-D0" This is remarkable in the network of.

For this reason, before the connection to the public wireless communication network is completed, the timeout at the time of accessing the home page from the application (browser) on the wireless LAN terminal side occurs first, and in fact, Although access to the home page is possible, a message may be displayed to prevent access to the desired home page on the wireless LAN terminal. It is not possible to know whether the connection to the public wireless communication network is time consuming or time-consuming, or cannot access the desired home page depending on the user. Not good. On the wireless LAN terminal side, although the timer of the application has timed out and an indication that access to the home page is not possible, the wireless communication device has access to a public wireless communication network, which is also useless.

Moreover, in the wireless LAN which is the conventional wireless communication system mentioned above, there also exists a problem shown below.

When the radio communication apparatus in the mobile vehicle connects to the public radio communication network, the radio state between the radio communication device and the public radio communication network changes depending on the position of the vehicle, so that the connection is not necessarily successful. In addition, a public wireless communication network using PPP (Point to Point Protocol), for example, PHS (Personal Handyphone System) or code division multiple access (CDMA: Code Division Multiple Access) system called "cdma2000 1xEV-D0" In a network, the time required for connection varies depending on the radio state, the number of radio users, and the like. However, the user in the mobile vehicle cannot know the radio state with the public radio communication network or the number of users of the public radio communication network. Therefore, the user first attempts to connect to the Internet via the public wireless communication network. However, when the wireless communication device is outside the service right of the public wireless communication network, for example, the user's wireless communication terminal I can't access the Internet. In addition, when the radio communication apparatus is in a place where the traffic of the public radio communication network is congested, the response is very slow even if the user's radio communication terminal accesses the Internet.

In other words, since the user cannot know the radio status between the radio communication device and the public radio communication network and the number of users of the public radio communication network, the reason why the user cannot connect to the Internet or the response is bad even if the user accesses it There was a problem of unknown cause.

However, in the above-mentioned conventional wireless communication system, there are also problems shown below.

When connecting to the Internet from a mobile wireless communication device in a mobile vehicle by a request from a wireless LAN terminal, a cellular phone network, which is a public wireless communication network, is used, but the communication speed of the cellular phone network is not sufficient compared to wireless LAN and the like, and is comfortable. It is difficult to provide an internet access environment. In addition, the communication speed becomes slower when the radio state between the cellular phone network becomes worse depending on the position of the vehicle, or when there are a large number of cellular telephone users who use the same base station outside the mobile vehicle.

Recently, the cdma2000 1x-EVDO (hereinafter referred to as "EV-DO") system has been developed as a next generation high speed wireless communication system. The EV-DO method is a method in which the cdma2000 1x method, which is extended to the cdmaOne method and corresponds to the third generation method, is further specialized in data communication to speed up the transmission rate. Here, "EV" means Evolution and "DO" means Data Only.

In the EV-DO scheme, the configuration of the uplink air interface from the radio communication terminal to the base station is almost the same as that of the cdma2000 1X scheme. In the downlink air interface configuration from the base station to the radio communication terminal, the bandwidth defined by 1.23 MHz is the same as the cdma2000 1x method, while the modulation method, the multiplexing method, and the like are greatly different from the cdma2000 1x method. In the modulation scheme, QPSK, 8-PSK, and 16QAM can be switched in accordance with the downlink reception state in the wireless communication terminal in the EV-DO scheme for QPSK and HPSK used in the cdma2000 1x scheme. As a result, when the reception state is good, a low error tolerance and a high transmission rate are used, and when the reception state is poor, a low transmission rate but a high error tolerance is used.

In addition, the multiplexing method for simultaneously performing communication from one base station to a plurality of wireless communication terminals is not a code division multiple access (CDMA: Code Division Multiple Access) used by the cdmaOne method or the cdma2000 1x method. Time division multiplexing which divides by / 600 seconds and performs communication with only one wireless communication terminal within that time, and switches between wireless communication terminals to be communicated at every unit time to perform communication with a plurality of wireless communication terminals. Use time division multiple access (TDMA).

The wireless communication terminal measures the carrier-to-interference ratio (hereinafter referred to as "CIR: Carrier to Interference power ratio") of the pilot signal as a downlink reception state from the base station to be communicated with, and receives the next reception from the variation. The reception state of the timing is predicted, and the base station is notified of the expected "maximum transmission rate that can be received below a predetermined error rate" as a data rate control bit (hereinafter referred to as "DRC: Data Rate Control bit"). The predetermined error rate here is usually about 1%, depending on the system design. The base station receives DRCs from a plurality of wireless communication terminals, and determines which wireless communication terminal the scheduler function in the base station communicates with each time division unit, but the communication with each wireless communication terminal is basically a wireless communication. Use the transmission rate as high as possible based on the DRC from the terminal.

The EV-DO scheme enables a transmission rate of up to 2.4 megabits per second (Mbps) per sector in the downlink by the above configuration. However, this transmission rate is the sum of the data communication amounts with a plurality of radio communication terminals connected to one base station in one frequency band and one of a plurality of sectors, which are usually transmitted when a plurality of frequency bands are used. The rate also increases. See, for example, Japanese Patent Laid-Open No. 2002-300644.

Apart from the EV-DO system, wireless LANs have also been developed to expand the available area of LANs, which are networks in companies and homes. In particular, wireless LANs standardized by IEEE802.11b have a transmission rate of up to 1 lMbps. And a communication area with a radius of 50 to 100 m. Higher transmission speeds, lower access points, lower prices for mobile terminals, and the wider spread of ADSL in the home are also becoming widespread. In addition, for use in other outdoor areas, individual spot services have been started at extremely limited places. In other words, the wireless LAN can provide a higher transmission speed although the service area is narrower than that of the EV-DO system.

On the other hand, wireless LAN services in vehicles that ride relatively long, such as buses and trains, have also been considered, and mobile devices are provided with a communication device having a communication means of a wireless LAN and a communication means of a cellular phone, and a notebook PC or the like in a vehicle. By connecting to a wireless LAN and connecting to the Internet outside the vehicle by using a cellular telephone network, it is possible to connect from the notebook PC in the vehicle to the Internet network outside the vehicle. When using a wireless LAN in a vehicle, the provider of the service performs an authentication procedure to prevent an unrelated person from connecting wirelessly, and encrypts the information transmitted by the user so as not to inadvertently leak it to another user. Needs to be. Usually, in a wireless LAN, encryption key (WEP), MAC address registration, etc. are methods for preventing another user from inadvertently connecting to an access point. In the case of a wireless LAN service in a vehicle or the like, wireless LAN cards and the like are not distributed to the person to be used, so the user cannot be restricted by MAC address registration. For this reason, the method of notifying a user beforehand about the encryption key according to an access point, and making it set to the terminal used by a user is taken. In addition, when the service itself is charged, when a user wirelessly connects to the wireless relay device, a specific portal site is displayed, and user authentication by user name and password is also possible.

The encryption by the encryption key in the above-described wireless LAN is usually only one for one access point. For this reason, users who are connected to one access point use the same encryption key. Among users who use the same access point, the security limit is low and there is a risk that information being wirelessly communicated is read. In order to make security more secure, it is necessary to set different encryption information, authentication information, etc. for each user. In the case of using the normal WEP key and the authentication procedure, at least for the first time, the user uses an input means such as a keyboard while viewing the terminal screen while viewing the paper containing the previously distributed password information and authentication information. In this case, password information and authentication information such as a user name and password in the authentication procedure may be input. Usually, in a mobile vehicle such as a bus or a tram, people are sitting at a distance to touch the shoulders. Under such circumstances, the contents of the paper containing the previous password information and the authentication information are easily displayed to the person sitting next to them, and the security is not secured, and the user is stored in a bus or a train that the user shakes. Entering an encryption key that is difficult to do correctly is cumbersome.

In recent years, mobile phones are in the direction of widening, and in the third generation mobile phones, the communication speed in the down direction has been realized at a maximum of 2.4 [Mbps] (see, for example, Japanese Patent Laid-Open No. 2002-300644). . In addition, in a LAN networked in a company or home, a wireless LAN is generally constructed because of its advantages. In particular, next-generation wireless LANs conforming to the IEEE802.1lb standard have been generally widely used in recent years, with the increase of the transmission speed, the low cost of access points and mobile terminals, and the spread of ADSL in general households. It is beginning to spread. In addition, spot services (hereinafter referred to as angular spot services) at each corner are also disclosed as outdoor use of mobile telephones using these wireless LANs.

In addition, the wireless LAN replaces what was connected between terminals with the conventional wired cable by the wireless, and has a high affinity with the LAN by the conventional wired cable. Against this background, the mainstream wireless LAN is compliant with IEEE802.11b, and its transmission rate is raised to 11 [Mbps] at maximum. In addition, since the area of one access point in such a wireless LAN is as small as a radius of 50 to 100 [m], each spot service of a cellular phone using these wireless LANs is a service in a very limited place. It is limited.

On the other hand, although the transmission speed of mobile telephones has been increasing over a wide bandwidth year by year, the transmission speed is still slow compared to wireless LAN. However, the service area of one access point is as large as a radius of 2 [km].

In addition, in the wireless LAN, as in the case of a cellular phone, there is a technology of mobile IP that allows a mobile node to continuously access without changing an IP address while installing many access points and navigating these access points. It is spreading. These mobile IPs include a Home Agent, which is a router having an interface on the mobile node's home link, and an Foreign Agent, which is a router having an interface on the link of the mobile node's moving destination. The mobile node also acquires a care-of address on the link of the moving destination, and registers the room address as the moving address of the moving destination with the home agent. On the other hand, the home agent encapsulates the packet transmitted to the mobile agent and transmits the packet to the room address, thereby changing the mobile node's IP address without changing the mobile node's IP address. Packets can be sent to

In addition, in the ITS (Intelligent Transport System) in which a car navigation system and a wide area traffic management system are fused, wireless communication of a car navigation system is aimed at, and a mobile telephone is connected to transmit and receive e-mails and the like. And internet access are possible. In addition, since the hard disk can be lowered and high-speed access is possible compared to a CD (Compact Disk) or a DVD (Digital Versatile Disk), road information of a car navigation system can be stored from a DVD to a HDD (Hard Disk Drive). Is moving to form. In addition, a system using wireless is also realized as a method of updating road information.

By the way, even if it is possible for the user using the wireless LAN service in the vehicle to check a predetermined timetable about moving vehicles such as a bus or a train, it is driving information such as which neighborhood it is currently traveling. It is not known in real time. In addition, when a delay occurs due to traffic conditions or the like, the user cannot grasp in real time how it affects the departure time or arrival time at a desired station or stop.

 In FIG. 4, when the wireless communication device 3 receives an access request (packet) from the wireless LAN terminal 2, the wireless communication device 3 refers to the destination of the packet and determines whether the destination is an external network (step S1). . Here, when the destination is not the external network, the corresponding server (for example, the WEB server unit 35) in the wireless LAN 1 is accessed (step S11).

As a result of the determination in step S1, when the destination is the external network, the flow advances to step S2 to determine the connection status with the external network. If the connection with the external network has already been completed, the access request to the external network is transmitted to the external network via the mobile terminal unit 32 (step S10).

As a result of the determination in step S2, if it is not connected to the external network, the flow advances to step S3 to initiate a connection with the external network and store the access request received from the wireless LAN terminal 2 to the storage unit 34. It saves (step S4).

Next, the wireless LAN terminal 2 serving as the originator of the access request returns a message indicating that it is connecting to the external network (step S5).

As a result, "in connection" is transmitted (step S23). If the PPP connection fails (step S24), the wireless communication device 3 transmits a "connection failure" to the wireless LAN terminal 2 as an external network connection status notification (step S25). As a result, the wireless LAN terminal 2 first displays a message indicating that it is connecting to the external network, notifies the user that it is connecting to the external network, and then a message indicating that the connection to the external network has failed. The user is informed that the connection to the external network has failed.

FIG. 6 shows a sequence chart when the connection to the external network is successful in the communication control processing in the wireless LAN 1 described above. In this example of FIG. 6, similarly to FIG. 5, the wireless LAN terminal 2 requests access to the WEB server 6 on the Internet 5 (step S21). By this access request, the radio communication apparatus 3 starts PPP connection processing with the cellular phone base station 4 (step S22), and simultaneously informs the wireless LAN terminal 2 of the external network connection status. As a result, "in connection" is transmitted (step S23). If the PPP connection is successful (step S31), the radio communication device 3 transmits an access request to the web server 6 to the cellular phone network (step S32). As a result, an access request from the wireless LAN terminal 2 to the WEB server 6 is executed.

In addition, the wireless communication device 3 may transmit "connection completion" to the wireless LAN terminal 2 of the external access request source as the external network connection status notification by the completion of the PPP connection. Thereby, in the wireless LAN terminal 2 of the external access request source, a message indicating that the connection to the external network is successful is displayed, and the user is notified that the connection to the external network is successful.

Next, a third embodiment will be described. In this third embodiment, the wireless communication device 3 caches a screen of a web page of an address requested by the wireless LAN terminal 2 in a period during which the wireless communication device 3 is in connection with an external network. If so, the cache data is displayed on the wireless LAN terminal 2. 10 is a block diagram showing the configuration of the radio communication apparatus 3 according to the third embodiment of the present invention. In FIG. 10, the wireless communication device 3 further includes a cache unit 42 in the configuration of FIG. 3. The cache unit 42 has a function of storing accessed page data. When the external network connection status notification of step S5 shown in Fig. 4 is performed, the control unit 33 stores the page data of the same address as the request in the wireless LAN terminal 2 of the external access request source. If it has been stored, the corresponding page data of the cache section 42 is transmitted.

This page data is received and displayed by the wireless LAN terminal 2 of the access request source. In addition, by receiving the page data, the wireless LAN terminal 2 prevents the occurrence of a timeout when accessing a Web page. As a result, the cached page screen is displayed until the connection of the external network is completed, so that anxiety of the user at the time of waiting is alleviated, and when the connection with the external network is completed, the latest page is displayed.

Next, a fourth embodiment will be described. Unlike the first to third embodiments described above, the fourth embodiment inquires of the external network connection status from the wireless LAN terminal 2 to the wireless communication device 3. In this fourth embodiment, the wireless LAN terminal 2 holds not only the wireless LAN terminal 2 but also an operable program. This program is an autonomous action computer program for realizing the function of inquiring the external network connection status from the wireless LAN terminal 2 to the wireless communication device 3.

Next, referring to Fig. 11, the operation of the fourth embodiment will be described. 11 is a sequence chart showing a flow of communication control processing in the wireless LAN 1 according to the fourth embodiment of the present invention.

In Fig. 11, first, the wireless LAN terminal 2 requests access to the WEB server 6 on the Internet 5 (step S41). By this access request, the radio communication apparatus 3 starts the PPP connection process with the cellular phone base station 4 (step S42), and simultaneously stores the program held in the radio LAN terminal 2. Transmit (step S43).

Subsequently, upon receiving the program, the wireless LAN terminal 2 of the external access request source executes the program and periodically transmits an external network connection status request to the wireless communication device 3 (step S44). When the radio communication device 3 receives the external network connection status request, it responds with the current connection status. In the response of step S45, since the PPP connection has not yet been completed, "connecting" is returned. Thereby, in the wireless LAN terminal 2 of the external access request source, a message indicating that the external network is being connected is displayed, and the user is notified that the external network is being connected.

Subsequently, when the PPP connection is completed (step S46), the radio communication device 3 transmits an access request to the WEB server 6 to the external network (step S47). In addition, upon completion of the PPP connection, the radio communication device 3 transmits "connection complete" as a response to the external network connection status request (step S48). Thereby, in the wireless LAN terminal 2 of the external access request source, a message indicating that the connection to the external network is successful is displayed, and the user is notified that the connection to the external network is successful.

According to the fourth embodiment described above, the external network connection status can be obtained autonomously from the wireless LAN terminal side.

In the fourth embodiment described above, the wireless LAN terminal 2 may have a program in advance.

In addition, when there is an access request from the wireless LAN terminal 2 to the external network, the wireless communication device 3 does not transmit the access request to the external network immediately after completion of the PPP connection, but after completion of the PPP connection, The access request may be sent to the external network, provided that the external network connection status request is received from the wireless LAN terminal 2 of the external access request source. Thereby, even if the wireless LAN terminal 2 cancels the access request, it is prevented from transmitting a wasteless packet (access request) to the external network.

In addition, when the wireless LAN terminal 2 holds the transmitted external access request and receives the completion of the connection with the external network, the wireless LAN terminal 2 transmits the access request again, and the wireless communication device 3 according to the access request. The access request may be transmitted to an external network.

As mentioned above, although the Example of this invention was described above with reference to drawings, a specific structure is not limited to this Example, The design change etc. of the range which do not deviate from the summary of this invention are included.

For example, in the wireless LAN terminal 2, the notification means for notifying the status of the wireless connection with the external network is not limited to displaying the above screen. The wireless LAN terminal 2 may notify the status of the wireless connection with the external network by the lighting of the display lamp. Alternatively, the voice may be notified of the state of the wireless connection with the external network.

In addition, the wireless LAN 1 may be built in an installation environment in which a home LAN or the like is fixed.

The public wireless communication network for access to the outside may be a wireless communication network in which a communication connection protocol other than PPP is used.

Further, if the radio communication terminal always receives and notifies the connection state with the external network, the user can confirm the connection state before requesting access to the external network.

As described above, according to the present invention, when a wireless communication terminal used by a user accesses an external network of a wireless communication device such as the Internet via a wireless communication device connected to a public wireless communication network, The user's anxiety can be reduced by notifying the user of the connection status with the public wireless communication network. As a result, it is possible to obtain an excellent effect of improving the reliability of the user for the wireless communication service and contributing to the development of the wireless communication service.

A block diagram showing the configuration of the wireless LAN terminal 2 according to the embodiment of the present invention is shown in FIG. Since this description is already described, it is omitted here.

However, add the following. The control unit 22 has various network service functions such as an electronic mail function and a home page browsing function (WEB browser function). In addition, as a means for notifying the user of the status of the wireless communication connection, the wireless communication device 3 displays wireless state information showing a wireless state (state of the external access wireless communication line 101) between the wireless communication device 3 and the external network. 24) and a function of displaying the number of users (the number of terminals) of the external network on the display unit 24. The radio state information and the number of use terminals are information referred to by the user of the wireless LAN terminal 2 when using the external network. In the following description, the radio state information and the number of terminals used are collectively referred to as external NW (NetWork) usage information.

13 is a block diagram showing the configuration of the radio communication apparatus 3 according to the embodiment of the present invention. In FIG. 13, the wireless communication device 3 uses a wireless LAN access point unit 231, a mobile terminal unit 232, a control unit 233, a storage unit 234, a WEB server unit 235, and an external NW. An information update unit 236 is provided.

The wireless LAN access point unit 231 transmits and receives a wireless signal with each wireless LAN terminal 2, establishes a wireless communication line for each wireless LAN terminal 2, and performs data communication.

The mobile terminal unit 232 transmits and receives a wireless signal with the external network cellular phone base station 4, establishes a wireless communication line 101 for external access, and performs data communication. In addition, the mobile terminal unit 232 has a function of measuring radio state information indicating a radio state with an external network. The radio state information includes, for example, a received electric field strength, an allocation amount of a radio transmission band, and the like. In addition, the mobile terminal unit 232 detects the number of wireless LAN terminals 2 (number of terminals used) for performing data communication using an external network.

The control unit 233 processes data transmitted and received by the wireless LAN access point unit 231 and the mobile terminal unit 232, respectively, and controls each unit of the wireless communication device 3. The storage unit 234 is accessed by the control unit 233 to store various data. The WEB server unit 235 establishes a home page for providing to the wireless LAN terminal 2.

The external NW usage information updating unit 236 obtains external NW usage information (wireless state information or the number of terminals used) from the mobile terminal unit 232 and stores it in the storage unit 234. The external NW usage information updating unit 236 periodically acquires the external NW usage information from the mobile terminal unit 232 and updates the external NW usage information stored in the storage unit 234.

The control unit 233 has a function of relaying communication between the wireless LAN terminal 2 and the outside of the wireless LAN system 1. The control unit 233 also has a function of notifying the wireless LAN terminal 2 of external NW usage information stored in the storage unit 234.

Next, with reference to FIG. 14, operation according to communication control in the wireless LAN system 1 according to the fifth embodiment of the present invention will be described. Fig. 14 is a sequence chart showing the flow of processing in accordance with notification of internal and external NW usage information of communication control processing in the wireless LAN system 1 according to the fifth embodiment of the present invention.

As a normal process of the radio communication apparatus 3, the mobile terminal unit 232 detects external NW usage information (wireless state information or number of terminals used) every predetermined period, for example, every second. In addition, the external NW usage information updating unit 236 receives the external NW usage information from the mobile terminal unit 232 by a predetermined period, for example, a period longer than a detection period by the mobile terminal unit 232 (for example, three seconds). And external NW usage information stored in the storage unit 234 is updated.

In Fig. 14, first, the wireless LAN terminal 2 starts a wireless LAN connection (step S201). Then, authentication information is transmitted to the wireless communication device 3 to perform authentication procedure (step S202). As this authentication information, the unique identification information recorded in the ticket of the vehicle 210, the arranging ticket for fare payment, the prepaid card for fare payment, etc. can be used. Alternatively, a private card, for example, a credit card number may be used.

Subsequently, upon receiving the authentication information from the wireless LAN terminal 2, the control unit 233 of the wireless communication device 3 verifies whether the authentication information is legitimate, and if it is legitimate, determines that authentication is possible (step S203). ). Subsequently, in the case where authentication is possible, the control unit 233 reads the external NW usage information stored in the storage unit 234 at a predetermined cycle and transmits it to the wireless LAN terminal 2 (step S204). Preferably, the wireless LAN terminal reads the external NW usage information from the storage unit 234 in a period (e.g., every three seconds) that is longer than an update period of the external NW usage information by the external NW usage information updating unit 236. Send to (2).

When the control unit 22 of the wireless LAN terminal 2 receives the external NW usage information from the wireless communication device 3, the control unit 22 displays the received external NW usage information on the screen of the display unit 24. Each time the controller 22 receives the external NW usage information, the control unit 22 updates the screen display contents of the display unit 24 according to the received external NW usage information (step S205). As a result, the user can determine whether to attempt to connect to the external network based on the radio state between the radio communication apparatus 3 and the external network or the number of terminals used. For example, when the radio state is poor, access to the external network is stopped. Alternatively, when the number of the use terminals is large, access to the external network can be attempted after the number of use terminals is reduced.

The above-described processes of steps S204 and S205 continue to be executed until the wireless LAN connection of the wireless LAN terminal 2 ends. Subsequently, when the wireless LAN terminal 2 terminates the LAN connection, the wireless communication device 3 stops the notification of the external NW usage information (steps S206 and S207).

According to the fifth embodiment described above, since the external NW usage information (radio state information between the wireless communication device 3 and the external network, or the number of terminals used in the external network) is notified to the wireless LAN terminal 2 and notified, The user may determine whether to attempt to access an external network based on the external NW usage information. As a result of this, for example, when the radio state is poor, the user can be expected to refrain from accessing to the external network, so that the connection to the external network is efficiently performed, thereby reducing the processing capacity and power consumption of the radio communication apparatus 3. It becomes possible to use efficiently.

In addition, since the user can know that the cause of poor access to the external network is due to a poor wireless state or a large number of terminals, the anxiety is reduced. In addition, since the user can grasp the external NW usage information in front of himself, it is very easy to use.

Next, a sixth embodiment will be described. Unlike the fifth embodiment described above, the sixth embodiment requests external NW usage information from the wireless LAN terminal 2 to the wireless communication device 3. In the second embodiment, the wireless LAN terminal 2 holds not only the wireless LAN terminal 2 but also an operable program. This program is a computer program of autonomous action type, and has a function of requesting external NW usage information from the wireless LAN terminal 2 to the wireless communication device 3 and a function of executing control for notifying external NW usage information. It is to realize.

Next, with reference to FIG. 15, the operation of the sixth embodiment will be described. FIG. 15 is a sequence chart showing a flow of processing corresponding to notification of internal and external NW usage information of communication control processing in the wireless LAN system 1 according to the sixth embodiment of the present invention.

Also in the sixth embodiment, as in the above-described first embodiment, as a normal process of the radio communication apparatus 3, the mobile terminal unit 232 detects the external NW usage information at a predetermined period, and also uses the external NW. The information update unit 236 periodically acquires external NW usage information from the mobile terminal unit 232 to update the external NW usage information of the storage unit 234.

In Fig. 15, first, the wireless LAN terminal 2 starts a wireless LAN connection (step S211). Then, authentication information is transmitted to the wireless communication device 3 to perform authentication procedure (step S212). When the control unit 233 of the wireless communication device 3 receives the authentication information from the wireless LAN terminal 2, the control unit 233 verifies whether the authentication information is legitimate, and determines that authentication is possible if it is legitimate (step S213). ). Subsequently, in the case where authentication is possible, the control unit 233 transmits the program held in the storage unit 234 to the wireless LAN terminal 2 (step S214).

Upon reception of the program, the wireless LAN terminal 2 activates the program, and periodically requests the external NW usage information from the wireless communication device 3 (steps S215 and S216). Upon receipt of this request, the control unit 233 of the wireless communication device 3 reads the external NW usage information stored in the storage unit 234 and transmits it to the wireless LAN terminal 2 (step S217).

When the wireless LAN terminal 2 receives the external NW usage information from the wireless communication device 3, the wireless LAN terminal 2 displays the received external NW usage information on the screen of the display unit 24. Each time the radio state information is received, the screen display contents of the display unit 24 are updated according to the received external NW usage information (step S218). As a result, the user can determine whether to attempt to access the external network based on the external NW usage information (radio state information between the external network or the number of terminals used in the external network).

The process of said step S216-S218 is continued until the wireless LAN connection of the wireless LAN terminal 2 is complete | finished. Subsequently, when the LAN connection is terminated, the wireless LAN terminal 2 ends the program (steps S219 and S220).

According to the sixth embodiment described above, the external NW usage information can be obtained autonomously from the wireless LAN terminal.

In the sixth embodiment described above, the wireless LAN terminal 2 may have a program in advance.

Next, a specific display example of the external NW usage information in each of the above-described embodiments will be described. 16-19 (d) is a figure which shows the example of display of external NW usage information.

FIG. 16 is a diagram illustrating a configuration example of the display screen 24a of the display unit 24 of the wireless LAN terminal 2. In the example of FIG. 16, the external NW usage information screen 2202 is displayed together with the web screen 2201 on the display screen 24a. The external NW usage information screen 2202 is a screen on which external NW usage information is displayed. The external NW usage information screen 2202 is set to a size in which external NW usage information can be recognized by the user. Preferably, the screen is as small as possible. Thereby, the external NW usage information can be notified on the display screen 24a without disturbing other displays. In addition, the external NW usage information screen 2202 may be called and terminated at any time by a predetermined operation of the operation unit 25.

17 is a diagram illustrating a first configuration example of the external NW usage information screen 2202. In the example of FIG. 17, the received electric field strength is used as radio state information in the external NW use information. In Fig. 17, the received electric field strength is displayed in three levels in the display area 2302 together with the display 2301 of the antenna. In the example of FIG. 17, the reception electric field strength is level 2. As a result, the level of the received electric field strength becomes a target of the radio state between the radio communication apparatus 3 and the external network, so that the good / bad of the radio state is apparent at a glance and is very easy to understand.

18A and 18B are diagrams illustrating a second configuration example of the external NW usage information screen 2202. In the examples of Figs. 18A and 18B, in addition to the configuration of Fig. 17 described above, the allocation amount of the radio transmission band is further used as the radio state information. In addition, the number of terminals used in the external NW usage information is used. In FIGS. 18A and 18B, the allocation amount of the radio transmission band is indicated by the size of the display bar 2311. In addition, the number of terminals used is displayed numerically in the display area 2312. As a result, the user can grasp how much wireless transmission band can be used.

19A to 19D are diagrams illustrating a third configuration example of the external NW usage information screen 2202. In the example of Figs. 19A to 19D, in addition to the configuration of Fig. 17 described above, the allocation amount of the radio transmission band is further used as the radio state information. In addition, the number of terminals used in the external NW usage information is used. In FIGS. 19A to 19D, the allocation amount of the radio transmission band is level-displayed in three stages by the number of display bars 2321. For example, in FIG. 19A, there is one display bar 2321, and it is indicated that the allocation amount of the radio transmission band is level 1. FIG. In addition, in Fig. 19B, two display bars 2321 are shown, indicating that the allocation amount of the radio transmission band is level 2. In addition, in FIG.19 (c) and FIG.19 (d), there are three display bars 2321, and it shows that the allocation amount of a radio transmission band is level 3. As shown in FIG.

The predicted data communication rate based on the allocation amount of the radio transmission band and the number of terminals used is displayed by the size of the effective display portion of the display bar 2321. The predicted data communication rate is obtained by dividing, for example, the allocation amount of the radio transmission band by the number of terminals. For example, in Figs. 19A and 19C, all of the display bars 2321 are valid displays, meaning that the entire allocation of the radio transmission band can be used by one terminal. . In addition, in Fig. 19B, approximately half of the display bar 2321 is an effective display, meaning that approximately half of the allocation amount of the radio transmission band can be used by one terminal. In addition, in Fig. 19D, about one quarter of the display bar 2321 is an effective display, meaning that one quarter of the allocation amount of the radio transmission band can be used by one terminal.

On the other hand, when FIG. 19 (a) and FIG. 19 (b) are compared, in FIG. 19 (a), the total allocation of the radio transmission band can be used by one terminal, and in FIG. 19 (b), Although approximately half of the allocation amount of the radio transmission band can be used by one terminal, in FIG. 19 (a), the allocation amount of the radio transmission band is level 1, whereas the allocation of the radio transmission band of FIG. 19 (b) Quota is level 2. Therefore, as a predicted data communication speed, it turns out that FIG.19 (a) and FIG.19 (b) are about the same grade. 19 (a) and 19 (c), the total allocation of the radio transmission band can be used by one terminal, but in the case of FIG. 19 (a), the allocation of the radio transmission band Is level 1, the allocation amount of the radio transmission band of FIG. 19C is level 3, and it can be seen that FIG. 19C shows that the predicted data communication speed is high. 19 (c) and 19 (d), the allocation amount of the radio transmission band is all level 3, but since the effective display portion is often shown in FIG. It can be seen that the predicted data communication speed of FIG. 19C is faster than that of (d). In other words, when the predicted data communication speed of FIG. 19C is 1, FIG. 19A is about 1/3, FIG. 19B is about 1/3, and FIG. 19D is (In addition, the allocation of the radio transmission band is proportional to the number of levels, and as described above, the calculation method of the predicted data communication rate is simply a case of dividing by the number of terminals used). .

As mentioned above, although the Example of this invention was described above with reference to drawings, a specific structure is not limited to this Example, The design change etc. of the range which do not deviate from the summary of this invention are included.

For example, in the wireless LAN terminal 2, the notification means for notifying the external NW usage information is not limited to displaying the screen described above. The wireless LAN terminal 2 may notify the external NW usage information by lighting up the display lamp. Alternatively, the notification may be made by voice.

Further, based on the external NW usage information, a specific message may be notified of the state of the usage environment of the external network. For example, "the use environment of the current external network is very good", "the use environment of the current external network is good", "the use environment of the current external network is bad", "it is outside" Notify or voice the message.

In addition, the wireless LAN system 1 may be built in a fixed installation environment, such as a home LAN.

The wireless communication network for access to the outside may be a wireless communication network in which a communication connection protocol other than PPP is used.

As described above, according to the present invention, when a wireless communication terminal used by a user accesses an external network such as the Internet via a wireless communication device connected to a public wireless communication network, the wireless communication device and the public wireless communication network are provided. By notifying the user of the radio status with the network, the user can determine whether to attempt to access an external network based on the radio status. As a result of this, for example, when the wireless state is poor, the user can be expected to refrain from accessing to the external network, so that access to the external network is efficiently performed, thereby efficiently using the processing power and power consumption of the wireless communication device. It becomes possible. In addition, it is possible to reduce anxiety of the user when using an external network.

According to the present invention, by notifying the user of the number of wireless communication terminals performing data communication using a public wireless communication network, the user can determine whether to attempt to access an external network based on the number of terminals. have. As a result of this, for example, when the number of terminals is large, the user can be expected to refrain from accessing the external network, so that access to the external network is efficiently performed to efficiently use the processing power and power consumption of the wireless communication device. It becomes possible. In addition, it is possible to reduce anxiety of the user when using an external network.

FIG. 22 is a block diagram showing the configuration of the management apparatus 307 shown in FIG. 20.

In FIG. 22, the communication unit 351 performs data communication via the Internet 5. For example, the mobile vehicle 210 via the WEB server 6 on the Internet 5, the mobile radio communication device 3 in the mobile vehicle 210 via the mobile phone network, and the router 312 of the bus center 311. It is possible to transmit and receive data with the mobile radio communication apparatus 3 and the like.

The cache server 352 stores Web pages on the Internet 5 estimated to have high access frequency. If a web page is requested, the web page is output.

The cache database 353 stores management information (URL, update date, etc.) about the web page stored in the cache server 352.

The cache update control unit 354 executes update control of web pages stored in the cache server 352.

The running vehicle cache management unit 355 grasps the web pages accumulated in the second cache server 337 of the moving vehicle 210 (driving vehicle) which contributes to the running. In addition, the grasped content is reflected to the cache server 352. That is, Web pages accumulated in the second cache server 337 are also stored in the cache server 352.

The running vehicle cache updating unit 356 executes processing for updating the second cache server 337 of the running vehicle. When the update source of the web page provider is updated with respect to the mobile vehicle 210 in service | operation, the update occasion updates from the said mobile vehicle 210 about the mobile vehicle 210 waiting by the bus center 311 etc. When the request was received.

The web access frequency aggregation database 357 accumulates information such as a travel route, a travel time zone, a URL access frequency list, and the like. 23, the structural example of the web access frequency aggregation database 357 is shown. In FIG. 23, for example, in the case of the travel time zone "6: 00-10: 00" of the travel route 1, the access frequency of URL1 is 100, the access frequency of URL2 is 98, the access frequency of URL3 is 80, and the like. The access frequency list is created based on the result of the access frequency measurement by the web access frequency measuring unit 340 of each mobile vehicle 10.

Next, the operation in the above-described embodiment will be described.

First, with reference to FIG. 24, the operation when the mobile radio communication apparatus 3 in the mobile vehicle 210 in operation receives a request for access to a web page from a user will be described. FIG. 24 is a flowchart showing a flow of processing executed by the mobile radio communication apparatus 3 shown in FIG. 21 upon reception of an access request to a Web page.

In Fig. 24, first, a user who is riding on a mobile vehicle 210 executes a request for access to a Web page on the Internet 5 using a wireless LAN terminal 2. When the control unit 333 of the mobile radio communication device 3 receives this access request (step S3101), it instructs the Web access frequency measurement unit 340 to register. By this instruction, the Web access frequency measuring unit 340 identifies the requesting web page and the identifier (for example, the MAC-ID or the mobile radio communication apparatus 3, etc.) that specifies the wireless LAN terminal 2 requesting access. The identifier distributed by the service member, etc.) is registered in its own measurement table, and the number of access users of the web page is counted up by one (step S3102).

The control unit 333 also searches the second cache server 337 to determine whether or not the requested Web page is stored (steps S3103 and S3104). When the request Web page is stored in the second cache server 337, the web page is read from the second cache server 337 and transmitted to the wireless LAN terminal 2 of the request source (step S3110).

On the other hand, when the request Web page is not accumulated in the second cache server 337, the control unit 333 searches the first cache server 336 to determine whether or not the request Web page is accumulated ( Steps S3105, S3106). When the requested web page is stored in the first cache server 336, the web page is read from the first cache server 336 and transmitted to the wireless LAN terminal 2 of the request source (step S3111). .

As a result of the search, if none of the first and second cache servers 336 and 337 has a request Web page accumulated, the control unit 333 communicates with the mobile terminal network by the mobile terminal unit 332. The state is determined (step S3107). If it cannot connect to the cellular phone network, it transmits an inaccessible message to the requesting wireless LAN terminal 2 informing that the request web page cannot be accessed because it cannot connect to the cellular phone network (step S3109). .

On the other hand, when it is possible to connect to the cellular phone network, the corresponding WEB server 6 on the Internet 5 is accessed to obtain a request Web page (step S3112). Next, the acquired request Web page is registered in the first cache server 336 (step S3113). The acquired request Web page is also sent to the requesting wireless LAN terminal 2 (step S3114).

The number of access users for each Web page measured by the Web access frequency measurement unit 340 is collected by the management apparatus 7 at the bus center 311 or the like and reflected in the Web access frequency aggregation database 357.

As described above, Web pages on the Internet 5 accessed in the past are stored in the first cache server 336. When the same web page is accessed again, the web page of the first cache server 336 is returned to the user. As a result, the frequency of accessing the Internet 5 using the cellular phone network is reduced, so that the communication load using the cellular phone network can be reduced, thereby improving accessibility when accessing the Internet from within a mobile vehicle. In addition, the communication cost can be reduced.

In addition, since the web page on the Internet 5 estimated to have high access frequency is stored in the second cache server 337, the second cache server 337 is connected to the first cache server when a web page request from a user is received. By searching ahead of 336, the search time can be shortened.

Next, with reference to FIG. 25, the operation according to the cache update by the management apparatus 307 is demonstrated. FIG. 25 is a flowchart showing the flow of cache update processing by the management device 307 shown in FIG. 22.

In FIG. 25, first, the cache update control unit 354 of the management device 307 checks the update status of a web page registered in the cache database 53 at an arbitrary cycle, and the WEB server 6 The updated state of the memory is determined (steps S3201 and S3202). When the update of the web page is detected, the cache update control unit 354 acquires the updated web page from the web server 6, and updates the web page of the cache server 352 (step S3203). ). Next, the cache update control unit 354 updates the update date and time of the update Web page of the cache database 53 (step S3204).

Subsequently, the running vehicle cache management unit 355 determines the presence or absence of the moving vehicle 210 in operation using the updated Web page based on the Web access frequency count database 357 (step S3205). And, if there is a corresponding mobile vehicle 210, the driving vehicle cache update unit 356, in order to update the second cache server 337 of the mobile vehicle 210, to the mobile vehicle 210 The update Web page is sent (step S3206).

Next, the cache update control unit 339 of the mobile vehicle 210 that has received the update Web page updates the web page of the second cache server 337 by the update Web page (step S3301). Subsequently, the update is reflected in the cache database 338 (step S3302).

As described above, the management apparatus 307 monitors the update status of the web page and reflects the update to the cache server 352 if there is an update. In addition, the second cache server 337 is updated only for the mobile vehicle 210 in operation in which the updated web page is used. As a result, it is possible to efficiently update the cache contents of the mobile vehicle 210 in operation, and it is not necessary to monitor the update status of the web page from each mobile vehicle 210 in operation. The load can be reduced.

FIG. 26 is a flowchart showing the flow of the update processing of the second cache server 337 for the mobile vehicle 210 before travel. Next, with reference to FIG. 26, the operation according to the update of the 2nd cache server 337 with respect to the mobile vehicle 210 before driving is demonstrated.

In FIG. 26, first, when the mobile radio communication apparatus 3 and the router 312 in the mobile vehicle 210 are connected via the LAN cable 313 in the bus center 311, the mobile radio communication apparatus 3 The LAN cable access unit 341 executes communication connection processing via the LAN cable 313 (step S3401). Subsequently, when a flight attendant inputs an update request of the second cache server, the cache update control unit 339 transmits an update request message of the second cache server to the management device 307 (steps S3402 and S3403). This update request message includes the vehicle identifier of the mobile vehicle 210.

Subsequently, when the management device 307 receives the update request message, the running vehicle cache update unit 356 causes the mobile vehicle 210 to next bus based on the vehicle identifier included in the update request message. The travel route and the travel time until it arrives at the center 311 are acquired from a travel planning database (not shown) (steps S3501 and S3502). The travel route and the travel time acquired here take on the service performed until the next update time of the second cache server 337.

Subsequently, the driving vehicle cache updating unit 356 refers to the web access frequency aggregation database 357 and sets a web page set (for example, based on the URL access frequency list corresponding to the driving route and the driving time obtained in step S3502). URL list) is created (step S3503). In this Web page set, Web pages of the highest access frequency (for example, from 1st to 3rd) are designated.

Subsequently, the driving vehicle cache updating unit 356 creates cache database data for the mobile vehicle 210 based on the created web page set. The created cache database data is then transmitted to the mobile vehicle 210 (step S3504). Upon receiving this cache database data, the cache update control unit 339 of the mobile vehicle 210 updates the cache database 338 (step S3404).

Subsequently, the running vehicle cache updating unit 356 of the management device 307 reads the corresponding web page from the cache server 352 based on the web page set, and the mobile vehicle 210 as the second cache accumulated data. (Step S3505). Upon receiving the second cache accumulated data, the cache update control unit 339 of the mobile vehicle 210 updates the second cache server 337 (step S3405). Next, the cache update control unit 339 transmits an update completion message to the management device 307 (step S3406). When receiving this update completion message, the running vehicle cache update part 356 of the management apparatus 307 complete | finishes a process as update completion (step S3506).

As described above, the management device 307 performs the update processing of the second cache server 337 for the mobile vehicle 210 waiting in the bus center 311 or the like based on the Web access frequency aggregation database 357. Run This update process will be described in detail. For example, the access frequency in the URL access frequency list of the next travel route and the travel time zone is stored in the bus center 311 in advance in the second cache server 337 of the waiting mobile vehicle 210. Shall be to the second place. Thus, in the example of Fig. 23, in the travel time zone " 6: 00 to 10: 00 " of the travel route 1, Web pages of URL1 and URL2 are stored in the second cache server 337 before the corresponding travel. On the other hand, even in the same service route 1, when the service time zone is "10:00 to 16:00", Web pages of URL1 and URL4 are stored in the second cache server 337 before the service.

In this way, for the mobile vehicle 210 before the operation, the second cache server 337 in operation is updated by updating the second cache server 337 based on the same service route and the past access frequency in the time zone in accordance with the next operation. 337) the hit rate can be increased. Because the same driving route is also expected to be accessed by the same person and the same person in the same time zone and the same page is accessed for the same purpose, the same driving route also has a web page with high frequency of past access in the time zone. This is because they are most likely to be accessed.

For example, in the case of a vehicle following a route from a residential area to a station, the time zone "6:00 to 10:00" is the time zone for commuting and attending school, and the news is for the purpose of collecting information at the beginning of the day. Web pages that provide information such as weather and weather are more likely to be accessed every day.

On the other hand, the important passengers in the time zones "10: 00-16: 00" are housewives, and it is expected that Web pages providing shopping information and hobby information will be similarly accessed.

Therefore, if a web page having high past access frequency according to each operation is accumulated in the second cache server 337 before the operation, the hit rate of the second cache server 337 is considered to be high. As a result of this, the frequency of accessing the Internet 5 is reduced, so that the frequency of use of the cellular phone network is reduced.

As described above, according to this embodiment, since the web page on the Internet 5 accessed in the past is stored in the first cache server 336, when the same web page is accessed again, the first cache server 336 ) 'S Web page is available. As a result, the frequency of accessing the Internet 5 using the cellular phone network is reduced, so that the communication load using the cellular phone network can be reduced, and the internet access environment in the mobile vehicle is improved.

In addition, since the web page on the Internet 5 estimated to have high access frequency is stored in the second cache server 337, when the user receives a web page request from the user, the second cache server 337 receives the first cache server. By searching ahead of 336, the search time can be shortened.

In addition, with respect to the mobile vehicle 210 before driving, since the web page according to the next operation is previously stored in the second cache server 337, a cache having a high hit rate can be configured.

In addition, since the second cache server update operation during the operation using the mobile phone network only needs to perform a web page updated during the operation, communication load using the mobile phone network can be minimized.

In addition, by reflecting the number of access users for each web page measured in the mobile vehicle 210 in the web access frequency count database 357 for each operation, the result of the access frequency measurement for each operation is determined in a subsequent vehicle operation. 2 Can be reflected in the contents accumulated in the cache server. As a result, an optimal cache is configured, and the hit rate of the second cache server 337 is improved.

In addition, the second cache server 337 can be further optimized by classifying the access frequency for the web page by weekday, weekday, holiday, and the like, and making a database.

As mentioned above, although the Example of this invention was described above with reference to drawings, a specific structure is not limited to this Example, The design change etc. of the range which do not deviate from the summary of this invention are included.

For example, the control unit 333 of the mobile radio communication apparatus 3 may not only list the web pages stored in the first cache server 336 or the second cache server 337 but also the wireless LAN terminal 2. Control to display may be performed. As a result, the user can grasp the cached Web page, which improves the convenience of accessing the Web page.

Embodiments of the present invention relate to a communication system including a wireless device provided on a bus. The radio apparatus has a function of a base station apparatus to which a terminal apparatus used by a user in a bus is to be connected, and also has a function of a terminal apparatus connected to a base station apparatus installed outside the bus. In this example, the communication system in the bus is a wireless LAN and the wireless system with the outside of the bus is an EV-DO system. However, the wireless device is a combination of these terminals, which is used by a user and a base station apparatus installed externally. Build a communication system to relay between The communication apparatus according to the present embodiment uses the communication system only for a specific user. That is, in order to prevent the use of the communication system by an unspecified user, authentication is performed on the terminal device.

In order to pay the bus fare, a user contacts, for example, a payment card such as a prepaid card to a payment device provided in the bus. The wireless device writes information on the terminal device such as authentication information, encryption information, and frequency to be used on the payment card. The payment device that has finished the payment of the bus fare discharges the payment card. The user inserts a payment card into the terminal device, and the terminal device outputs a connection request to the wireless device based on the information about the terminal device written in the payment card. For example, the authentication information and the encryption information are used to generate a signal for the connection request, and the signal is output at the frequency to be used.

The wireless device executes an authentication process of the terminal device based on the signal, and permits connection if it is a terminal device owned by a regular user. Furthermore, data with the terminal device is transmitted to the communication system of the EV-DO system.

In that case, the second communication unit 424 corresponds to a base station apparatus as a wireless LAN. In addition, a second communication antenna 462 is provided for wireless communication.

The payment card 414 is a card for paying the fare of the bus. As described above, a prepaid card is exemplified. The user makes the payment card 414 contact the payment device 412 when getting on the bus. The reading unit 442 reads the information in the payment card 414, for example, the remaining amount of money, and performs the process of clearing the fare, and then the writing unit 444 writes the final remaining amount to the payment card 414. The writing unit 444 also writes information necessary for communication between the wireless device 410 and the terminal device 416.

The authentication information generation unit 434 generates authentication information, for example, a password, for the terminal device 416, and outputs the authentication information to the writing unit 444 for writing to the payment card 414. The cryptographic information generation unit 436 generates cryptographic information, for example, a secret key, for the terminal device 416, and outputs the cryptographic information to the writing unit 444 for writing to the payment card 414.

The storage unit 432 stores the generated authentication information and the password information when there is a connection request from the terminal device that generated the authentication information and the password information in the authentication information generation unit 434 and the password information generation unit 436. For use, it stores authentication information and password information. In addition, information necessary for processing the fare clearing, for example, a fare table, is also stored.

28 shows a data structure of information about the terminal device stored in the storage unit 432. Here, the "identification number" is a number for identifying the terminal device 416, and for example, an identification number of the user who owns the terminal device 416 is used. Here, it demonstrates with A1-AN. "Authentication information" is a password generated by the authentication information generation unit 434, which is exemplified here as B1 to BN. "Cryptographic information" is a secret key generated by the cryptographic information generation unit 436, which is exemplified here as C1 to CN.

This configuration can be realized in hardware by a CPU, a memory, or other LSI of a computer, and in software, by a program having a loaded reservation management function of a memory. The functional blocks realized are shown. Therefore, it is understood by those skilled in the art that these functional blocks are realized in various forms by only hardware, only software, or a combination thereof.

29 is a sequence diagram showing an authentication process. The user contacts the payment card 414 with the payment device 412 (S410). In order for the reading part 442 to read the content of the payment card 414, the payment device 412 performs payment processing (S412). In addition, the authentication information generation unit 434 and the password information generation unit 4434 generates predetermined information (S14). The writing unit 444 writes predetermined information into the payment card 414 (S416). The payment device 412 discharges the payment card 414 to the outside (S418). Next, the user inserts the payment card 414 into the reading unit 448 (S420). The reading unit 448 reads the information (S422), and outputs the read information to the authentication unit 450, the encryption unit 452, the communication unit 446, and the like. Based on the operation of the authentication unit 450 and the encryption unit 452, the communication unit 446 generates a packet for connection request (S424). The second communication unit 424 receives the packet, and the authentication unit 438 confirms the information (S426). If the information is correct, the wireless device 410 permits communication to the terminal device 416 (S428). Thereafter, the wireless device 410 relays the data in the communication between the terminal device 416 and the data in the communication between the base station device 418.

30A to 30C illustrate the appearance of the terminal device 416 of FIG. 27. For the terminal device 416, FIG. 30A is viewed from the front of the slope, FIG. 30B is viewed from the rear of the incline, and FIG. 30C is viewed from the rear of the mountain. In addition, the card housing cover 470 is opened. Opening the card storage unit cover 470 enables the card storage unit 472 to withdraw various cards such as the payment card 414. When the card storing unit cover 470 is closed as shown in FIG. 30 (b), the payment card 414 accepted by the card storing unit 472 is fixed inside and written to the payment card 414 in wireless communication. The cipher information and authentication information are read into the terminal device 416. By setting the communication means with the card to be a non-contact type, it is possible to set the card irrespective of the vibration and shaking of the moving vehicle for the non-contact, even in the case of a small card without requiring different contact parts for each card.

The operation of the communication system 4100 according to the above configuration will be described. In Fig. 27, when a customer who has a payment card 414 boards a bus, when the payment card 414 is inserted into the payment device 412, payment according to the boarding is performed and the wireless device 410 is performed. The authentication information and password information newly generated by the authentication information generation unit 434 and the password information generation unit 436 are written into the payment card 414 by the writing unit 444. The same authentication information and encryption information are stored in the storage unit 432. When the payment card 414 is inserted into the card storage unit 472 of the terminal device 416, the reading unit 448 of the terminal device 416 receives the authentication information and encryption information which were written earlier from the payment card 414. The reading unit 452 encrypts the information to be transmitted to the wireless device 410 based on the cipher information.

Further, using the authentication information, authentication procedure with the wireless device 410 is executed. The terminal device 416 transmits information via the communication unit 446 and the antenna 464 for the terminal, and is received by the second communication antenna 462 of the wireless device 410 to connect the second communication unit 424. After that, the encryption unit 440 decrypts the signal, and the authentication unit 438 performs the authentication procedure, and determines that the password information and authentication information match the previously stored information in the storage unit 432, and if it matches, Permit. As a result, it is impossible for those who do not board the bus to receive the service using the wireless device 410. In addition, since unique cryptographic information and authentication information are used for each terminal, forgery and decryption of wireless information can be difficult to obtain, and it is possible to increase the safety of personal information of the occupant.

In addition, the information distribution in the communication system 4100 will be described in detail as follows. At the time of getting on, the password information generating unit 436 of the wireless device 410 generates new password information, and the authentication information generating unit 434 generates new authentication information and fills in the payment card 414. At the same time, it is stored in the storage unit 432. On the other hand, at the time of use, when the authentication information encrypted using the encryption information stored in the payment card 414 is first sent to the wireless device 410, the encryption unit 440 decrypts the authentication unit 438. In the authentication procedure, the authentication procedure is executed, with reference to the password information and the authentication information stored in the storage unit 432, to confirm that they match. By generating unique password information and authentication information for each card, it is possible to securely distribute and use the password information and authentication information. In addition, by discarding the information described in the payment card at the time of getting off, it is impossible to continuously communicate with the same cipher information and the same authentication information at the other terminal.

According to the present embodiment, in order to perform authentication of the terminal device by the authentication information written on the predetermined card, leakage of the authentication information can be prevented and safety can be improved. In addition, in order to notify the terminal device of the information of the frequency used by the wireless device in advance, the terminal device can reliably communicate with the wireless device to which connection is desired. In addition, since the card in which the authentication information is written is shared with the card used for payment of the fare, the user does not require possession of a new card.

The present invention has been described above based on examples. This embodiment is an illustration, It is understood by those skilled in the art that various modifications are possible for each of these components and the combination of each processing process, and that such modifications are also within the scope of the present invention.

In the present embodiment, the card accommodating portion 472 is described integrally with the terminal device 416. However, the present invention is not limited thereto, and may be detachable, for example. In this case, a separate solid card storage portion 472 is connected to the terminal device 416 by a USB cable or the like. According to this modification, the payment card 414 can also be read by the terminal apparatus 416 which is not equipped with the card storage part 472. In other words, the payment card 414 may be read.

In the present embodiment, the communication network between the radio apparatus 410 and the base station apparatus 418 has been described as an EV-DO system, but other radio communication means such as a simple portable telephone system may be used. According to this modification, this invention can be applied to various aspects. That is, it is only necessary to be able to access a network external to the bus or the like.

In the present embodiment, a description has been given by taking a bus as an example, but movements such as trains are inherently applicable to the provision of a wireless communication environment in a fixed facility. In addition, although the payment card 414 and the arranging ticket were given for the transmission of the authentication information and the encryption information, it may be a ticket issued in advance, another card always owned by an individual, a semiconductor memory, or the like. According to this modification, this invention can be applied to various aspects. That is, the predetermined information may be notified to the terminal device 416 by the predetermined card.

Distribution of authentication information and password information using the rearrangement right operates as follows, for example. The IC tag is used for the reorganization ticket itself, and authentication information and password information are written in the reorganization ticket at the time of ticketing. In addition, information on a bus stop etc. which boarded simultaneously is entered. At the time of use, similarly to the case of the payment card 414, the arranging ticket is put in the card storage section 472 of the terminal device 416, and the reading section 448 reads the authentication information and the cipher information written in the arranging ticket. . Furthermore, based on the rearranging ticket put into the payment device 412 at the time of getting off, the cipher information and authentication information which have been described are deleted from the storage unit 432, and the boarded bus stop read from the rearranging ticket and the current stop. The amount of money is calculated and displayed from the input information from the stop and the driver such as the number of adults, children and the number of people. The change of cash and the indication of the shortage are displayed for the cash input. In the type of bus card, even in the case of the post-closing type, the same processing as in the above-described rearranging ticket is possible.

 In the present embodiment, "frequency information" is described, but not only the frequency, but also the modulation scheme and the communication standards of the wireless communication between the wireless device and the terminal device (IEEE802.1la, IEEE802.1lb, IEEE802. 1lg, HiS WAN, wireless 1394, UWB, etc.) may be information related to wireless communication.

EMBODIMENT OF THE INVENTION The Example of the running management system in this invention is described in detail using drawing. First, in order to make understanding easy, the outline | summary of a running management system is demonstrated.

Wireless LAN services are established in public transport vehicles where a large number of passengers rise and fall, such as buses and trams. In these mass transport vehicles (hereinafter referred to as mobile vehicles), a wireless relay device having a wireless LAN communication means and a mobile telephone communication means is provided, and wireless communication is performed between a portable terminal such as a notebook PC in the mobile vehicle. By connecting to a LAN and connecting to a network outside the mobile vehicle by using a cellular phone network, it is possible to connect to the Internet network outside the mobile vehicle from a notebook PC or the like in the mobile vehicle.

In addition, as a service combining a mobile communication system such as a bus or a train and a wireless communication system, for example, in a bus using a general road, the running time depends on the congestion of the road, etc. The system which transmits information, such as a position and the departure time of a stop, and displays the latest operation | movement state in a stop via a center computer (host computer) etc. is also established. Similarly, a service for providing information on the operation status of a bus, a train or the like using the Web has also been realized. As a result, the person waiting for the bus at a stop or the like can know in advance how long the bus will arrive, thereby providing mental security to the passenger waiting for the bus.

35 is a configuration diagram of a communication system in a mobile vehicle. The radio relay device 512 'of the mobile vehicle 51' is connected to the network 54 via a 1x EV-DO (1x Evolution Data 0nly) base station 53, and provides the network 54 with Web information and the like. The WWW server 55 is connected. In addition, the wireless relay device 512 'inside the mobile vehicle 51' and the wireless LAN terminals 513, 514, and 515 carried by each passenger are provided with a wireless LAN access point unit (configured in the wireless relay device 512 '). 5125 is in the area of local network 52 '. Thereby, each passenger can take in the desired Web information from each WWW server 55 to each wireless LAN terminal 513, 514, 515 via the wireless relay device 512 '.

However, in the communication system shown in FIG. 35, each wireless LAN terminal 513, 514, 515 cannot take in the information regarding the stop which a passenger wants to get off. In other words, in the technology of the communication system shown in Fig. 35, there is no way of knowing how long the bus will arrive at a desired stop for a person riding on a bus or the like. In addition, the passenger who boarded the bus informs the crew of the getting off by pressing the button of disembarkation installed in the vehicle when the stop to be unloaded becomes the next stop, but when the vehicle is crowded or blinks When you are doing it, you may not be able to press the button to get off. In addition, the next stop is notified to the passenger by an in-vehicle broadcast informing the next stop or a bulletin board in front of the vehicle displaying the next stop. However, since various passengers ride simultaneously in a moving vehicle such as a bus, a person talks. If you can not hear the broadcast in the vehicle by the sound of the sound or depending on the sitting position may be a blind spot may not be visible. Or, if you are sitting in the back of the bus, you may not see the bulletin board if a tall person is standing in front of you, and you may not know the next stop.

In addition, if the bus is used every day, such as commuting or going to school, the next stop can be known by viewing the scenery outside without listening to or watching the in-vehicle broadcasts or bulletin boards. If you do not know the name of the next stop, you may not be able to determine whether you are going to get off. In addition, when a passenger is sitting and dozing, the on-board broadcast is missed and entered, and when the eyes are opened, a situation such as pressing the button of getting off in confusion in the scenery outside occurs, for example, just before trying to pass through the stop. When it is noticed, an undesired condition may occur in the operation of the bus, such as a driver may stop the bus by suddenly braking or suddenly change the lane.

Therefore, in the present invention, a mobile management system such as a bus or a train is notified to the portable terminal possessed by the passenger while riding, and the driving information and getting off information, thereby constructing a driving management system that is convenient for use by passengers. . EMBODIMENT OF THE INVENTION Hereinafter, the running management system in this invention is demonstrated in detail, referring drawings.

31 is a conceptual diagram showing the configuration of a service management system according to the present invention. In the driving management system of FIG. 31, the wireless relay device 512 of the mobile vehicle 51 is connected to the network 54 via the 1xEV-DO base station 53. In addition, the mobile vehicle 516 having the same configuration as the mobile vehicle 51 is also connected to the network 54 via the 1xEV-DO base station 517. The network 54 is connected to a data center 510 for centrally managing data relating to traffic information and a WWW server 55 for providing Web information. In addition, a wireless relay device 512 is provided in the mobile vehicle 51, and each passenger carrying the wireless LAN terminals 513, 514, and 515 is riding on the mobile vehicle 1. Moreover, the inside of the mobile vehicle 51 is in the area of the local network 52 of the wireless LAN access point part 5125 comprised in the wireless relay device 512. As shown in FIG.

The wireless relay device 512 further includes a 1xEV-DO mobile terminal unit 5120, a control unit 5121, a wireless LAN access point unit 5125, a WWW server unit 5126, a vehicle position information acquisition unit 5501, A configuration including a route information storage section 5252, a get-off reservation information update section 5503, a get-off reservation information notification section 5254, a get-off reservation information storage section 5255, a display section 5256, and an operation section 5257 It is. In addition, the configuration of the wireless relay device in the mobile vehicle 516 is also the same as that of the mobile vehicle 51. Therefore, in the following description, the wireless relay device 512 of the mobile vehicle 51 will be described.

The 1xEV-DO mobile terminal portion 5120 of the wireless relay device 512 can wirelessly connect to the 1xEV-DO base station 53 outside the mobile vehicle 1 via the antenna 5129. Further, the 1xEV-DO base station 53 is connected to the network 54 by wire, and is in a state capable of communicating with the WWW server 55 and the data center 510 existing on the network 54. In addition, the vehicle position information acquisition unit 5251 can specify the position of the vehicle through the antenna 5250 by GPS or the like (not shown). In addition, the get-off reservation page of the WWW server unit 5126 of the wireless relay device 512 can be accessed from the wireless LAN terminals 513, 514, and 515.

On the disembarkation reservation page of the WWW server unit 5126, the vehicle position information acquisition unit 5251 reads the vehicle position acquired and also reads the driving route information and the map information of the mobile vehicle 51 from the route information storage unit 5252. do. Then, display processing according to the position of the current mobile vehicle 51 is executed based on the driving route and the map information, and the positional information of the mobile vehicle 51 is displayed on the wireless LAN terminal 513 which has been accessed, for example. . In addition, when the stop scheduled to be selected from the wireless LAN terminal 513 is selected, the get off reservation information update unit 553 is an identifier (eg, for connecting to the Internet) that identifies the scheduled stop and the wireless LAN terminal 513. An IP address, a MAC address for identifying an information device connected to a LAN, or an identifier distributed by a wireless relay device, etc.) is stored in the reservation information storage unit 5255.

The getting off reservation information update unit 553 can be obtained from the vehicle position information acquisition unit 5251 and the route information storage unit 5252 of the mobile vehicle 51 each time the mobile vehicle 51 passes through the stop. On the basis of the next stop information that is present, the getting off schedule information stored in the get off reservation information storage unit 5255 is read, and it is determined whether or not there is a getting off schedule at the next stop. When there is a scheduled getting off, the getting off information is transmitted as a notification message to the wireless LAN terminal 513 corresponding to the identifier associated with the next stop. In the above, the case where the wireless LAN terminal 513 accesses the wireless relay device 512 has been described. However, when the wireless relay device 512 is accessed in the same manner with respect to the wireless LAN terminals 514 and 515, the wireless relay device is connected. The get off information from the device 512 may be received as a notification message.

FIG. 32 is an explanatory diagram showing a processing flow when any wireless LAN terminal executes a get off reservation for a wireless relay device in the service management system in FIG. 31. Therefore, the flow of performing the process of getting off reservation by using FIG. 31 and FIG. 32 is demonstrated. First, when the passenger who boarded the mobile vehicle 51 opens the reservation window of the wireless relay device 512 by the wireless LAN terminal which he carries, he selects the bus stop as a method of selecting the "stop route" or "map." Three methods of "selecting from" or "selecting from destination" are displayed (step S51).

If the item "Select from route map" is selected in step S51, the route map of the bus currently being boarded, the name of the bus stop, the estimated passing time, etc. are displayed, and for each bus stop, the " The "Get Off" button, the "Map" button for displaying a map of the area including the stop, and the "Information" button for displaying information near the stop are displayed on the screen (step S52). Here, when the passenger selects the "get off" button of the stop where the passenger is going to get off, the screen "Do you get off at ○○○?" For checking the getting off again is displayed (step S57). If the "Yes" button is selected on this screen, the disembarkation reservation at the stop corresponding to the disembarkation reservation information storage unit 5255 of the wireless relay device 512 is stored, and the disembarkation is released from the screen "stop ○○○" of the reservation completion. Reserved ”, and the getting off reservation is completed (step S58).

When the item " select from map " is selected in step S51, a map on which a route is written based on the current position of the moving vehicle 51 is displayed (step S53). Here, the letter of "pass" is added to the stop which has already passed. Further, by selecting the desired stop button (for example, "CCC"), an enlarged map including the selected stop "CCC" is displayed (step S56). Therefore, when the "Get off reservation" button is selected, the screen for re-confirming getting off reservation "Don't get off at ○○○?" Is displayed (step S57). If the "Yes" button is selected, the stop reservation at the stop corresponding to the stop reservation information storage unit 255 of the wireless relay device 512 is stored, and the stop reservation is made at the stop screen ○○○ of the reservation completion screen. Is displayed, and the getting off reservation is completed (step S58).

When the item " Select from destination " is selected in step S51, a screen for inputting a destination name is displayed (step S54). Thus, when the passenger enters the destination name and selects the "determination" button, the destination name and the nearest station name (for example, "CCC") are displayed (step S55). If the "Map Confirmation" button is selected, a map including the corresponding stop is displayed (step S56). In addition, when it is possible to display a destination in a map, it flashes on a map or displays it in a color different from another color, as the location of a destination is visually easy to recognize. At the same time, it is also possible to draw a line on the map indicating the route from the stop to the destination. When the "Get off reservation" button is selected, the screen "Do you get off at ○○○?" Screen for re-checking the getting off reservation is displayed (step S57). If the "Yes" button is selected, the drop off reservation at the stop corresponding to the drop off reservation information storage unit 255 of the wireless relay device 512 is stored, and the screen "reserved off at the stop CCC" is displayed. Then, the getting off reservation is completed (step S58).

In addition, about the estimated passing time between the stops described in the "Selection in the route map" screen of step S52, for example, each mobile vehicle shows the arrival, departure, and passing times of each stop at the 1xEV-DO wireless communication line network and network. When transmitted to the data center 510 via the 54, the data center 510 is driven afterwards based on the information of arrival, departure, and passing time obtained from the moving vehicle that first passed the same line. The estimated passing time of the moving vehicle can be estimated, and the scheduled passing time can be transmitted from the data center 510 to the moving vehicle 51.

When the reservation is stored in the getting off reservation information storage unit 5255, an identifier (for example, an IP address, a MAC address, a wireless relay device) that can identify the reserved wireless LAN terminal in addition to the stop reserved for getting off It is assumed that the identifier assigned from 512) is stored simultaneously. By storing the identifiers at the same time in this way, when the next stop becomes a stop which is scheduled to get off, it can be notified that an identifier (that is, a corresponding wireless LAN terminal) that is scheduled to get off at that stop is the stop where the car is getting off. have. The notification may also be executed by voice. Although not described here, a screen for changing or deleting the reserved stop other than the reserved reservation can be provided.

FIG. 33 is an example of the flowchart which shows the reservation notification process flow in the service management system of FIG. First, when passing through the stop where the moving vehicle 51 is located (step S511), the guidance broadcast of the next stop is started (step S512). Then, the get-off reservation information of the next stop is read from the get-off reservation information storage unit 5255 (step S513) to determine whether or not a get-off reservation is made (step S514). Here, when getting off reservation is made (No at step S514), the getting off reservation information notification part 5254 notifies the crew that there is a getting off reservation (step S515). In addition, by forcibly pressing the getting off button in the vehicle, the getting off button and the buzzer sound (step S516). In this way, all passengers are notified of the stop at the next stop while also prompting the crew to stop. In addition, a message indicating that the reserved stopper is reserved is notified to the getting-off reservation person (step S517). Then, an in-vehicle announcement broadcast is made to stop at the next stop (step S518).

In addition, when getting off reservation cannot be made in the judgment of the presence or absence of getting off reservation in step S514 (YES in step S514), it is judged whether it passed the predetermined stop as before (step S519). ) And the moving vehicle 51 is driven while executing the determination (step S520) of whether or not the get off button has been pressed. In addition, when passing through the predetermined stop, the process similar to the above is repeated, starting from the first step S511 for the next stop.

Fig. 34 is a diagram showing an example of notification of the next getting off stop displayed on the PDA (Persona1 Digital Assistant) by the driving management system. As shown in FIG. 34, in the PDA 5400 having the communication function of the wireless LAN, when the stop registered by the passenger as scheduled to get off becomes the next stop, the local network (from the wireless relay device 512 of FIG. 31). A message of that effect is notified via the wireless LAN of 52, and a notification message 5401 is displayed on the screen of the passenger PDA 5400 (for example, the wireless LAN terminal 513 of FIG. 31). At the same time, when the main body of the PDA 5400 vibrates or a sound or a message is pronounced from a speaker (not shown), the passenger who owns the PDA 5400 is informed that the next stop is a stop that is scheduled to get off.

Thereby, even if a passenger is dozing and sleeping, it is possible to prevent the situation that a person passes by and cannot get off at the planned stop. In addition, when the bus stops at the scheduled stop, the crew member gets off at the stop by checking whether the identifier of the PDA 5400 scheduled to be unloaded is the identifier of the wireless LAN terminal still existing in the mobile vehicle 51. You can check whether or not the scheduled passengers got off.

Here, a mode of transmitting a notification message from the wireless relay device 512 of FIG. 31 to the PDA 5400 of FIG. 34 will be described. For example, when the wireless LAN terminal 513 of FIG. 31 connects to the wireless relay device 512, it moves from the 1xEV-DO mobile terminal 5120 of the wireless relay device 512 via the antenna 5129. Radio waves are transmitted to the 1xEV-DO base station 53 outside the vehicle 51. Thereby, the software (for example, Java (registration) which displays the EV-DO antenna 5403 of the PDA 5400 which shows the connection state from the wireless relay device 512 to the 1xEV-DO base station 53 outside the mobile vehicle 1). Software) and the like, and a notification message is transmitted from the wireless relay device 512 to the wireless LAN terminal 513 (that is, the PDA 5400).

The EV-DO antenna 5403 of FIG. 34 accesses the wireless relay device 512 of FIG. 31 at any period, acquires display information of the antenna bar, and provides information on whether the next stop is a scheduled stop. Acquire. Here, when the next stop is a scheduled stop, a notification message 5401 for that purpose is displayed on the screen, and desired notification processing is performed for the owner of the PDA 5400. In addition, the software itself displaying the EV-DO antenna 5403 may hold the stop which is scheduled to get off, and may make the determination based on the information of the next stop reported by the wireless relay device 512 of FIG. In addition, the EV-DO antenna 5403 may be displayed and the next stop may be always displayed.

In addition, in the case of a passenger who always gets off at the same stop, such as commuting and attending school, the wireless relay device 512 is combined with an identifier (for example, MAC-ID) identifying a wireless communication terminal owned by the passenger and the stop. Is registered as the always getting off reservation information always getting off at the same stop. As a result, when the wireless communication terminal owned by the passenger gets on, the identifier of the wireless communication terminal is compared with the constant getting off reservation information stored in the getting-off reservation information storage unit 5255, and the identifier of the wireless communication terminal is obtained. If it is registered, it is treated as a reservation for getting off. This eliminates the need to set a disembarkation reservation every time a fixed passenger gets on, and reduces the load on traffic to the wireless LAN in the vehicle.

In addition, a device having a function portion related to getting off reservation setting and a function of an access point of a wireless LAN, such as the wireless relay device 512, is installed at each stop, and the stop reservation is registered at the wireless relay device installed at the stop. When the mobile vehicle 51 arrives, the stop reservation information may be transmitted from the wireless relay device at the stop to the wireless relay device 512 in the mobile vehicle 51. Thereby, reservation setting of the stop to get off can be performed while waiting for the arrival of the mobile vehicle 51 in the stop. In addition, when the mobile vehicle 51 to be boarded arrives, a notification message indicating that the mobile vehicle 51 to be boarded has arrived, and the mobile vehicle 51 to the wireless communication terminal of the bus stop where the bus is reserved. Information such as identification of the vehicle such as the displayed destination may be transmitted. As a result, in the stop where the moving vehicles of a plurality of lines stop, the passenger can ride the vehicle without finding and moving to the target moving vehicle 51.

In the above embodiment, the computer (subcomputer) mounted in the vehicle is a vehicle position information acquisition unit 5251, a route information storage unit 5252, a disembarkation reservation information update unit 5503, and a disembarkation reservation information notification unit 5254. ), But it is configured to function as the getting-off reservation information storage unit 5255, the display unit 5256, and the operation unit 5257, but all or part of this function is assigned to the host computer connected to the subcomputer via a communication network. It is good also as a structure.

In addition, in the embodiment of the present invention, the bus has been described as an example of a moving vehicle, but it is obvious that the present invention can be applied to other vehicles such as a train or the like. In the embodiment of the present invention, 1xEV-DO is described as an example of a public communication network outside the mobile vehicle, but other wireless communication means such as PHS may be used.

Next, when a vehicle, such as a bus, arrives at or passes through a stop, a specific embodiment for estimating the arrival time or departure time to the stop will be described. First, information, such as the arrival time and departure time of a stop, is uploaded from each vehicle to a management center. At this time, the weather information is uploaded to the management center.

Thereby, the management center estimates the time when each vehicle arrives at the next stop based on the arrival time and departure time of each vehicle. Further, the management center calculates the stop time at the stop from the time information acquired from each vehicle, and aggregates these time information according to each stop, time, weather, and the like. At this time, the management center estimates the time of arrival at the next stop based on the traveling time of the first passing vehicle traveling on the same route. In addition, in the vehicle which stops at a stop and the vehicle which does not stop at a stop, it determines with a different route, and estimates arrival time.

36 is a conceptual diagram for estimating the arrival time when the vehicle does not stop at the stop in the embodiment of the present invention. 37 is a conceptual diagram for estimating the arrival time in consideration of the number of passengers, the weather and the like at the stop in the embodiment of the present invention. 38 is a conceptual diagram of calculating the arrival time to the stop in the embodiment of the present invention.

In FIG. 36, the time YY2 (S + 1) when the vehicle 2 passes through the stop S and arrives at the stop S + 1 is estimated based on the vehicle 0 and the vehicle 1 which have first passed the same route. When vehicle 2 stops at the stop, vehicle 0 and vehicle 1 also use the data of the vehicle stopped at the stop. In addition, when estimating the arrival time to the distant station S + n, the stop time (rise time) of each station existing between the station S and the station S + n uses the statistical value accumulate | stored in the database. Run it. In addition, since statistical values in consideration of the number of passengers, time, weather, and the like of the station shown in FIG. 37 are accumulated in the database, the corresponding statistical values are obtained from the database to obtain the arrival time and departure time of each station.

Next, with reference to FIG. 38, the arrival time to a stop is calculated | required. In other words, the arrival time at the stop S + 2 is obtained by the following equation.

[Arrival time of stop S + 2] = [arrival time of stop S + 1] (T1 (S + 1)) + [stop time of stop S + 1] (W1 (S + 1)) + [stop S + Travel time from 1 to stop S + 2] (S1 (S + 2)).

39 is a conceptual diagram for estimating the arrival time when considering traffic conditions near the intersection in the embodiment of the present invention. As shown in Fig. 39, in the vicinity of the intersection, road conditions such as congestion are eliminated when the intersection is congested and exiting the intersection, or vice versa. For this reason, in the estimation of the traveling time, the estimation is performed by dividing the intersection as a branch point and before and after. In addition, in order to estimate the arrival time in consideration of such road conditions, each vehicle needs to upload the time at which the vehicle enters the intersection or the time at which the vehicle exits from the intersection to the data center.

In addition, when an accident occurs, the driver of the vehicle recognizing the corresponding accident uploads the location of the accident in GPS coordinates to the data center, and time-out according to the accident factor to the estimated time of arrival of the subsequent vehicle. Add the item to execute the correction process.

In addition, in the above description, although the arrival time and departure time of a stop and an intersection point were mentioned as the time to upload to a data center as an example, it is not limited to this. In addition, when considering the purpose of improving the accuracy of the estimation result of the arrival time or the departure time, it is preferable to divide the stations into finer sections, and to upload data for each section. This makes it possible to estimate the more accurate arrival time even when a longer distance than the stop between stations and a delay due to an accident is required.

40 is a conceptual diagram illustrating a state in which the estimated arrival time at the stop is displayed on the outside of the vehicle in the embodiment of the present invention. As shown in FIG. 40, by displaying the estimated arrival time to the stop on the outside of the vehicle, the passenger can know the approximate arrival time before boarding. It is also possible to provide the same visual information from a server on the Internet.

As described above, the driving management system system of the present invention establishes a wireless LAN in a vehicle such as a bus or a train, passes the wireless LAN to a station or a stop where the passengers in the vehicle get off. Provide information. For example, the information to be provided to the portable terminal is a notification of a stop or a station to get off, a notification of a passing time passing through a stop or a station. In the case of a train, when the portable terminal reads the designated ticket, the train station may automatically know the station or time.

When the getting off notification is executed for the portable terminal, the passengers on boarding the vehicle register the stop to be getting off using the portable terminal in advance. In doing so, the host computer executes the disembarkation notification at an appropriate timing after passing one of the stops to be disembarked to the portable terminal of the registered passenger. At this time, the position determination of the mobile vehicle executed by the host computer is most preferably performed by inquiring about a GPS, a map, or the like, but it may be judged by the information when the crew manually turns the recording tape for getting off.

In addition, although the host computer may be installed in the mobile vehicle or in the ground command station, the host computer does not produce a difference in the notification function. It is also possible to receive only the positional information from the ground command station and process the identification of the registered portable terminal in the moving vehicle. That is, various methods can be considered for the role sharing in the operation management system. In other words, the driving management system of the present invention comprises a host computer installed on the ground, a subcomputer mounted on the mobile vehicle, and a portable terminal owned by a passenger riding on the mobile vehicle. no.

Also, as a function such as car navigation, the current position of the moving vehicle is determined by the system of the ground host computer, and the passing time or the required time of the predetermined point is carried out using the current position data and the actual traveling speed data. It is also possible to notify. For example, when the pass time of the next stop is calculated by using data such as the time required for the bus running one time at the last stop passing time, it is possible to accurately predict the pass time of the stop by reflecting the road delay.

As described above, according to the radio communication system of the present invention, and the radio communication apparatus and radio communication terminal used in the radio communication system, the radio communication terminal used by the user connected to the radio communication apparatus accesses the Internet. When the radio communication apparatus uses the public radio communication network, the user's anxiety at the time of connection to the public radio communication network can be reduced.
